For this equation, we can let c = the value of one coupon
<span>4c = 108 - 76 </span>
<span>4c = 32 </span>
<span>c= $8
Hope this helped, and if it did I'd appreciate if you marked me as brainliest as I need it to get to a higher rank. If you need any more help, feel free to add me and/or message me :)

To convert 3/4 to a percent we need to convert 3/4 to a decimal and then multiply the decimal by 100. Lets do it:-
To convert a fraction to a decimal we have to divide the numerator by the denominator.
3/4
3 ÷ 4 = 0.75
Decimal = 0.75
0.75 × 100 = 75
75%.
So, 3/4 in percent form is 75%.
Hope I helped ya!! xD
Answer:
- <u>Option C. The Network C sample.</u>
Explanation:
The variability of a sample may be described by using some common statistics like the variance and the standard deviation.
The variance and the standard deviation measure the difference between the values of the data and the mean. The variance is the average square of those differences or deviations. The standard deviation is the square root of the variance.
Thus, both variance and deviations, being an average of the differences of the data from the mean contain the number of data in the denominator of the equation.
That lets you know to conclude that the larger the number of data (the larger the sample) the smaller the variance and the standard deviation, this is the lower the variability of the data.
Hence, Network C, which has the greatest number of voters sampled (1,800) is likely to have the least variability.
1 times 10^1=10
1 times 10^-1=1/10
1 times 10^-2=1/100
1 ten thousandth is 1/10,000, that is 1 times 10^-4
answer is
1*10⁻⁴
